What is setIsomorphicDir() _really_ supposed to do?

[fhisg]

Based on the Javadoc I assumed that com.smartgwt.client.util.Page.setIsomorphicDir(s) would redefine the URLs for all non-skin resources:

Specify the root directory for Isomorphic-supplied files.

This doesn't seem to be the case. I set

String moduleName = GWT.getModuleName();
Page.setIsomorphicDir(moduleName + "/sc1.0.10/");
Page.setSkinDir(moduleName + "/sc1.0.10/skins/Enterprise/");

But the URLs Smart GWT issues are as follows:

http://server/context/module/sc/modules/ISC_Core.js
http://server/context/module/sc/skins/Enterprise/load_skin.js
http://server/context/module/sc/skins/Enterprise/skin_styles.css
http://server/context/module/sc1.0.10/skins/Enterprise/images/Scrollbar/vscroll_start.png

The JavaScript and CSS resources are still served from the original URL. Is that a bug or is there some other method I need to call additionally?

Background: I try to set up caching as per http://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/docs/Caching.html with the help of URL rewriting.

P.S. I can't find the class com.isomorphic.servlet.FileDownload documented in the caching docs, where does it come from?

We're not sure which resources you're trying to affect, but you can't even call setIsomorphicDir() until after ISC_Core.js is loaded - ISC_Core.js is what *provides* the setIsomorphicDir() API.

The other resources you mention are affected by the skin dir - see the QuickStart Guide section on custom skins.

Docs for all server-side classes are in the server-side JavaDoc.

Yes, I get that. I understand that ISC_Core.js is not affected by setIsomorphicDir(). However, all other ISC_xxx.js files are also loaded from the standard /sc/modules/ path. I expected a modified path for subsequently loaded "modules".
Furthermore, is there a way to modify the path to ISC_Core.js to profit from the same caching infrastructure?

The other resources you mention are affected by the skin dir

That's what I expected but as my output shows only the skin images are loaded from the modified path. load_skin.js and skin_styles.css are loaded from the standard path eventhough I set setSkinDir().

All of the script loads you're considering here happen as a consequence of your GWT <inherits> of SmartGWT modules and skins, all before onModuleLoad() ever executes.

To affect these things, you use the FileLoader as mentioned in the Caching overview and related docs - a *JavaScript* API. When using the FileLoader, you use the *NoScript versions of SmartGWT modules to prevent the automatic loading of resources (since you'll do it via FileLoader).

Thanks for the explanations, appreciate it.
